I have sold my Dome in order to cover the cost of some important documents i am getting, so, after having an observatory, it is not easy to go back to set up and pack up every imaging night.........

I moved houses not long ago and had for two months a disassembled 3x3 shed, i am renting here and don't want anything permanently fixed to the ground, and, it needs to be cheap........ so budget is less than 800 for everything....

It helps that i have some material left from the deck that was holding the dome on the other house....

A couple of screws doesn't cut it, you need to fill every hole in the brackets with structural clouts or screws.
But what is holding the shed down is a concern also!
Roof - walls - to foundation to hold everything down
(Looking good though)

Can it fly? You bet! The major lift force is the wind blowing across the top surface, and it can get significant. Theoretically the best way to minimise the lift is to present an irregular surface to any wind direction ie a set of baffles running in cross directions.
